Great submission, I find myself spending a lot of time on this trying to merge similar elements! The game loop is simple yet effective, and it succeeds in keeping the player engaged with simple mechanics. I also think you managed to give it a perfect cozy atmosphere, congrats!
The only constructive criticism I could make is about the sequence of upgrades: it isn't really intuitive, and I had to memorize it all in order to play properly. Maybe using elements of a single category (such as animals, or plants) could have helped you with a more natural ordering. Anyway, it's not a big deal at all! Again, congratulations for the level of polishing and thanks for the game!
